2 Claims.

My invention relates to a new and impro-ved tubular belt and more particularly to a tubular stitched belt which is made of knitted fabric.

One of the objects of my invention is to pro- 5 vide an improved method for making a belt which will not twist and which does not require pressing in order to shape the same.

Other objects of -my invention will be set forth in the following description and drawing which l illustrates a preferred embodiment thereof it being understood that the above general statement of theobjects of my invention is intended merely to. generally explain the same and not to limit it in any manner. I

lr Fig. 1 is a plan view showing the mechanism for turning the fabric and for performing other operations thereon.

Fig. 2 is a sectional view on the line 2--2 of i .,Fig. 1. Fig. 3 is a sectional View on the line 3--3 of Fig. 1.

Fig. 4 is a side elevation showing the first operation in forming the article.

Fig. 5 is a plan view showing the second operation.

Fig. 6 is a plan View showingthe completed article.

Fig. 7 is a sectional View on the line '7 7 of V Fig. 6. 'A The article is made upon a suitable sewing machine having a hollow arm l, to which a hollow cap 2 is detachably secured. For this purpose the cap 2 is provided with pins 3 which `llenter suitable recesses or sockets in the arm 1,

and a spring latch 4 is provided for detachably connecting the cap 2 tothe arm 1. A plate 5 is connected to the arm 1 by means of screws 6a. Said plate 5 fits into depressions which are formed in the arm 1 and in the cap 2.

" The plate 5 is provided with openings 6 and 7 through which the feed-dogs of the sewing mechanism can operate and said plate is also provided wth openings 8 through which the sewing Amachine needles can pass. The machine utilized is of the two-needle type which forms a well known stitch of the type which is shown in Figs. 6 and 7. f

As shown in Fig. 6, the completed article has ,the form of a pointed tube. In the rst opera- 'tion a piece of material M which has been suitably shaped is doubled, and the curved front portions of the edges of said piece of material M are connected by ordinary stitches 10.

This piece of material is now turned so as to produce the blank shown in Fig. 5. In the turned (Cl. 11E-262) blank shown in Fig. 5 the stitches 10 are invisible and they are located along the line 10a.. Said `blank has a pointed end 1 Referring more particularly to the mechl anism, an arm l2 isconnected to the outer end @D of the cap 2 by set-screws ll.4 The connection between the arm 12 and the cap 2 is adjustable. The arm 12 has a. flange l5 to which a plate i6 is connected by means lof set-screws 17.' A plate 18 is connected in any suitableman- 65 ner to the free or right-hand end of the plate 16 in Fig. 1.

Referring to Fig. l, the longitudinal outline of the plate 18 is indicated by the dotted lines 18a. y

Referring to Figs. l and 2, the free or righthand end ofthe plate 18 is formed with ears 18e which project downwardly from the plate 18, and said ears 18e have inwardly turned ends.r

Guides 20 andvZOa are provided with integral lugs 21 and 21a which are adjustably connected to the plate 15 by means of set-screws 22 and 22a.

These set-screws 22 and 22a pass through the plate 15 and they'also enter the plate 16.

Referring to Fig. 5, it will be noted that the entire blank does not have its edges connected by the stitches 10, along the line 10a. Only one end of said blankis provided with the stitches along the line 10a, in order to provide the pointed end 10.

In order to connect to each other the remaining portions of the edges of the blank shown in Fig. 5, said blank is led through the mechanism illustrated in Figs. 13. The edges of said blank are led under the lugs 18o and the inturned edges of said lugs cause the edges of said blank to be inwardly turned as generally shown in Fig. 5, at the right-hand side of the line 10a.l The lnturned edges of the blank slide along the top of the member 18. The members 20 and 20a also operate to inwardly turn the edges of the blank M so as to produce the necessary taper.

As shown in Figs. 1 and '7, the stitching mechanism forms an ordinary stitch having longitudinal stitch elements or thread portions 9 and 9a, which are connected by transverse stitch elements 9c.

Hence, a belt of any desired length can be made, and a buckle or the like can be connected to the rear end of the belt. A belt is thus produced which has the necessary pointed end, and due to the tubular construction of the belt, the belt does not twist and the method of manufacture makes it unnecessary to press the belt in order to shape the same. It is merely necessary to first shape the piece of cloth or other material so' 'i seL loo

which is used for making the belt, so that the main portion of said piece of material has parallel edges, and one end of said piece of material has a tapered form, as shown in Fig. 4.

Referring to Fig. 7, it will be noted that the main portions of the edges of the blank abut each other and 'that said edges are connected to each other and to the body of the blank by means of the stitch elements which are shown in Fig. 7.

It will be noted that the blank shown in Fig. 5 is pulled through the turning members under suitable tension so that the main portions of the edges oI" the blank are inturned, and the stitch shown in Fig. '7 is formed, While the blank is under suitable longitudinal tension'. When the blank of cloth is in the initial flat condition,

the body portion of said blank has edges which are parallel to each other and said edges have a tapered end. It is sufficient to merely connect the edges of said tapered end by means of the stitches 10 or in any other suitable manner, so as to provide the Vblank with a tubular pointed end. Referring to Fig. 5, it will be noted that the blank is provided with a sleeve-like pointed end before the remaining portions of the edges of said blank are connected to each other. I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions can be made without departing from lits spirit.

I claim:

1. A method of producing a tubular belt having a pointed end from a flat blank which has a tapered end, which consists in connecting the edges of said tapered end to each other by means of stitches, then turning the tapered end so that said stitches become invisible and the blank ispigovided With a tapered point, and -then inwardly turning the remaining portions of the edges of said blank and connecting them to each other. 2. A method of producing a tubular belt having a pointed end from a flat blank which has a tapered'end, which consists in connecting the edges of said .tapered end to each other by means of transverse stitches, then turning said tapered end, and then subjecting the blank to longitudinal tension While inwardly turning the remaining portions of the edges of said blank Without causing said remaining portions to overlap, and connecting said remaining portions of the edges to the body of the blank by means of stitches having longitudinal stitch elements which pass through` said edges and the body of the blank, said longitudinal stitch elements being connected by transverse stitch elements which extend transversely across said edges.
